This invention relates to devices used for cleaning surfaces, and moreparticularly for cleaning windows after painting.

()ne of the objects of this invention is to provide a device in whichthe blade of socalled safety-razorscan be used, having a handle memberand having clampin means by which the razor-blade can be firmly held.

Another object is to provide a device of this type with yieldinglyconnected clamping means on a handle.

another object is to provide a yieldingly connected clan'iping-end on ahandle with controlling means of an elastic nature, as a spring,interposed between the handle and the yielding clamping member.

Other objects will appear from the following description and appendedclaims as well as from the accompanying drawing, in whicl Fig. 1 is atop plan view of a scraper of a simple form embodying this invention.

Fig. 2 is a fragmentary section on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary section similar to the one illustrated in Fig.2, having a flat or leaf-spring for controlling the yieldingblade-holder instead of coil-springs indi-' cated in Figs. 1, 2 and f.

Fig. at is a cross section through the bladeholder and the blade on linel4=of Fig. 1.

In painting windows it is quite a task and practically impossible toavoid getting paint over the glass in the window, and it is a commonpractice to remove the paint from the glass of the window, after thepainting by scraping, for which purpose worn-out razonblades are veryuseful.

One of the principal objects of this invention is therefore to provide apractical, useful, and handy tool, by which such razor-blades can beused more readily and easily.

As illustrated in the drawing, the razorblade 5 is disposed between twohingedly connected plates 6 and 7. The hinge-pivot 8 is formed by theends of the wire 9. This wire 9 is mounted in a handle 10, Other wires11 are secured to the first-named wire 9 at 12, as by soldering,welding, or in any other similar suitable manner. The free ends 13 ofthe wires 11 extend over the blade holder, formed by the plates 6 and 7,and are spaced above the holder, an that SCRAPER.

springs 14 can be disposed between the holdor and the ends 13.

The springs 1 1 have the tendency to force the holder with the insertedblade 5 downwardly, however allowing a yielding of the holder with theblade when the handle is pressed downwardly in excess of the normaltension of the springs, thereby preventing to, a great extent ascratching or marring of the window-glass. i

A screw 15 1's provided for clamping the two plates 6 and 7 together,and thereby causing a firm holding of the razor-blade 5, making anexchange of the razor-blade easy and convenient.

To facilitate a quickand proper locating of the razor-blade betweenthetwo plates 6 and 7, small pins 16 are preferably pro vided, asillustrated in Fig. 1, to engage in the perforations of suchrazor-blades.

A slightly modified form of yielding means between the handle and therazorblade-holder is illustrated in Fig. 3, in form of a flat orleaf-spring 17. Such and other slight modifications can, of course,easily be arranged within the spirit and. scope of this invention.

Having thus described my invention, I

claim:

1. In a scraper, a blade-holder, a handle having means to movablyconnect the bladeholder to the handle, and elastic means between theblade-holder and the handle to allow a yielding of the movably connectedblade-holder in relation to the handle.

2. In a scraper, a blade-holder, a handle embodying means for hingedlyconnecting with the blade-holder and other means to extend to a pointover the hingedly connected blade-holder, and yielding means between thehandle and the holder.

3. In a scraper, a blade-holder consisting of hingedly connected membersbetween which a scraping blade can be firmly held and means, for firmlyholding the hingedly connected members clamped together, a liandleembodying means for connecting with the hinge of the blade-holder andmeans to extend to a point over the hingedly connected blade-holder, andyielding means between the handle and the holder.

In testimony that I claim the foregoing as my invention 1 have sinned inname.
